I have mentioned using a shoulder stock/pod to aid panning with long lenses. I finally got some shots of the system that I have put together and used with my Sigma 150-600 C in the examples in this thread. It was put together using one of those cheap 15mm tube systems sold for building DSLR Video rigs. I think it cost around £25 from Amazon, my daughter bought it as a gift.
For the first shoot I just taped a temote release to the front handel. I will be mounting a coulpe of buttons in it for future use, and might even use an AR15 style pistol grip at the front instead.
Using this rig makes panning smoothly so much easier, just like swinging a shotgun really. I can even manage a full 180 degree swing from my wheelchair. Not something I can do with the shotgun, because it's a lot shorter stocked I think. Normally the sjotgun is held across the body more, while the camera pod is held out square from the shoulders, more like a pistol in a Weaver stance.
